COOKING-RANGE.

Specification of Letters Patent No. 24,4192, dated June 21, 1859.

To all whom i may concern:

Be it known that I, IV. G. RUGGLEs, of lVorcester, in the county of lVorcester and State of Massachusetts, have invented a new and Improved Cooking-Range; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, in whichh Figure l, is a vertical section of my invention taken in the line oo, Fig. 2. Fig. 2, a vertical section of do, taken in the line y, y, Fig. l. Fig. 3, a horizontal' section of do, taken in the line e, a, Fig. l. Fig. 4, a horizontal section of do, taken in the line m, no", Fig. l. Fig. 5, a horizontal section of do, taken in the line y, y, Fig. l. Fig. 6, a horizontal section of do taken in the line e', e', Fig. l.

Similar letters of reference indicate corresponding parts in the several figures.

The invention relates to an improvement on a cooking apparatus for which Letters Patent were granted to me bearing date May 18th 1858, and it is designed to carry out more perfectly in the present invention the principles involved and set forth in the former one.

To enable those skilled in the art to fully understand and construct my invention I will proceed to describe it.

A, represents the case of the range which may be of rectangular form. rlhis case is represented with single walls but itmay have double walls and the space between filled with any suitable non-conducting substance to retain the heat. Within the case A, at one side, a fire chamber B, is placed. This fire chamber may be encompassed with fire brick a, and a space C, is allowed back of the fire chamber and the back of the case A, which forms the lower part of the smoke stack or upright flue. At one side of the fire chamber B, an oven D, is formed, which oven is provided with a central hollow shelf o, provided with a vertical partition plate c, as shown clearly in F ig. 5. This oven D, also has a bottom iiue chamber CZ, provided with a vertical plate e, as shown in Fig. 6, and both the lire chamber B, and oven D, are covered with a plate f, provided with the usual pot holes g, a chamber z, being formed under the part of said plate that covers the oven, and a vertical partition plate z', placed therein. The chamber h,

communicates with the fire chamber B, by means of a damper j, and the hollow shelf Z) communicates with the tire chamber by a damper both of which are shown in Figs. l and 2. The chamber h, shelf b, and chamber d, communicate with the upright flue C, by means of dampers Z, see Figs. 4, 5 andV 6.

E, is a. damper by which a direct draft may be obtained with the upright iiue C.

The oven D, and fire chamber B, have doors F, in front so that both may be completely inclosed within the case A. The space Gr, within the case A, above the tire chamber B, and oven D, may, when desired, be employed for an oven. This `space or oven G, has a horizontal central and hollow shelf fm, placed within it, the interior of which shelf communicates with a vertical flue chamber n, at one side of the space or oven Gr. The lower part of the flue chamber a, communicates with the fire chamber' B, and a valve o, is placed within to cut off the communication when necessary,-see Fig. l. The hollow shelf m, of the oven G, has a horizontal partition plate fitted within it, so as to give it a circuitous flue route, the upper part or chamber formed by the partition plate communicates with the flue chamber n, and the lower part communicating with a flue chamber n', directly back of n. The lower part of the flue chamber n, com municates with t-he upright flue O. The upper part of the flue chamber n, communicates with a chamber o which has a vertical partition plate go, within it. The back part of this chamber o, communicates with an upright flue H, the lower end of which communicates with flue C. The oven Gr, is provided with doors I, so that it may be fully inclosed. The shelf m, has a soap stone slab m', placed on it which serves as a heat retainer. A similar slab may if desired be attached to the shelf o, of the oven D.

The operation is as follows If it is desired to cook by boiling only, the dampers 7c, E, o, are closed and the draft passes up through the chamber It, around the inner end of the partition plate i, and into the upright flue or smoke stack C, as shown by the red arrows in Fig. 4. This arrangement it 'will be seen is precisely similar to an ordinary cook stove or range. In kindling the iire a direct draft is obtained by opening the damper E. In baking ordinary sized articles such as may be contained within the oven D, the dampers y', 7c, and Z, are opened,

sov

hollow shelf b, and chamber d, around the' ends of the partition plates c, e, into the flue or stack C. By this arrangement the oven D, will be thoroughly heated, the products of combustion passing over it, under it and through its center, as shown plainly in Fig. l. In using the oven D, the holes g, may be occupied with pots and boiling or broiling and baking may be done simultaneously, but, in case the oven G, is to be used, boiling must be dispensed with, although the lower 'oven D, may be used. In using the oven Gr, alone, the dampers la, E, are closed, and dampers j, o, opened. In the latter case the products of combustion pass through the chamber h, as usual and up the Hue n, through the hollow shelf m, and also through the chamber o, the products of combustion in the latter case passing directly into flue or stack H, while the products of combustion that pass through the hollow shaft m, enter the flue n, and pass down into C. It will be seen therefore that the oven Gr, is heated precisely similar to oven D,-no heat is lost or wasted, the fuel being consumed and the heat generated thereby applied in the most economical man- 'nel'.v This arrangement of cooking range admits of an air-heating apparatus being applied in a very economical way, for the oven G, when not in use may be used as the air heating chamber, cold air pipes being connected therewith, and' hot air pipes leading therefrom. The shelves m, b, may be so arranged as to admit ofbeing readily withdrawn, for the purpose of being cleaned, and also in case much space is required within the ovens, and when articles are being boiled and for the purposes herein shown and described.
